您需要像这样将@Validated添加到您的类中：
@RestController@Validatedclass Controller { // ...}更新 ：
您需要对其进行适当的配置..将此bean添加到您的上下文中：
@Bean public MethodValidationPostProcessor methodValidationPostProcessor() { return new MethodValidationPostProcessor(); }处理异常的示例 ：
@ControllerAdvice@Componentpublic class GlobalExceptionHandler { @ExceptionHandler @ResponseBody @ResponseStatus(HttpStatus.BAD_REQUEST) public Map handle(MethodArgumentNotValidException exception) { return error(exception.getBindingResult().getFieldErrors() .stream() .map(FieldError::getDefaultMessage) .collect(Collectors.toList())); } @ExceptionHandler @ResponseBody @ResponseStatus(HttpStatus.BAD_REQUEST) public Map handle(ConstraintViolationException exception) { return error(exception.getConstraintViolations() .stream() .map(ConstraintViolation::getMessage) .collect(Collectors.toList())); } private Map error(Object message) { return Collections.singletonMap("error", message); }}
